Anna is a supporting character in Pinocchio: The Series. She is a young girl with blue eyes and brown hair, which she wears in two braided pigtails secured with white hairbows. She also has two large pink roses positioned on the top of her head. Her clothing consists of a dress that is primarily yellow and red, with lavender stripes on both the top and bottom of the skirt, and she is depicted wearing pink blush and lipstick.

Anna is a friend to Pinocchio and appears to be a practical individual. When Pinocchio breaks her violin while trying to play it, Geppetto agrees to carve a new one using special wood from a magical tree. However, when presented with this new, strangely-shaped instrument, Anna refuses it, saying she does not want it because of its unusual appearance. She allows Pinocchio to keep the magical violin instead. Despite being friends with a living puppet and having encountered other supernatural entities like witches and vampires during her adventures, Anna expresses skepticism about the existence of mermaids.

One of Anna's notable abilities is playing the violin, an instrument she practices regularly. Her key relationships are primarily with Pinocchio and his creator, Geppetto, as she lives in the same community and interacts with them directly. Information regarding her background, motivations, character development, and specific role in the overall story is not available.
